Tungsten Copper W80 Rod
Tungsten copper W80 rod is composed of 80% W and 20% Cu so that high hardness and melting point characteristics of tungsten is more obvious. Its density is up to 15.15g/cm3, hardness reaches more than HB140, but due to less Cu, conductivity is decreasing to 34IACS%, softening temperature is ≥900℃,the bending strength is 980, the thermal conductivity is 190-210(wm/k) and the coefficient of expansion is 8.0-8.5(10-6K).
In the early 1960s, american researchers have been used tungsten copper as missile nozzle or rocket insert and jet vane at high temperature. Common materials could not work at such high temperature (even more than 3000℃), tungsten copper takes advantage of Cu evaporating taking away heat so that the whole temperature will decrease. With the development of aeronautics and astronautics, the requirements of tungsten copper will remarkably increase, which demands that it should have good properties, such as better strength and anti-ablation at high temperature.
Notice: It should be noticed that adjust the parameters when tungsten copper discharging or wire cutting, and the speed is lower than other materials. To avoid contacting with strong acid and alkali before electroplating, which will cause the metal grain shedding.
